Topic, question and claim
A topic names what a text concerns: library access, seed records or repair skills. A claim says something about that topic that could be accepted, challenged or qualified. “Library hours” is a topic; “A separate late-collection window would help some workers without displacing quiet study, if it can be staffed” is a claim. A main-point answer normally needs the relationship, not just the subject.
Begin by asking what question the passage answers. It might ask what should change, why something happens or how two methods differ. An explanatory passage can have a central account without recommending any policy. Conversely, an interesting opening example may merely introduce a larger argument. Count neither sentence position nor vividness as proof of importance.
ORIGINAL PRACTICE · 1
Original passage: The museum has added labels beside several objects, yet visitors still bend close to read them. Staff observed that the smallest print disappears into the grey background when the gallery lights are dimmed. Adding another panel would repeat the same difficulty. The immediate task is to improve contrast on existing labels, while preserving the low lighting required for sensitive objects. Once visitors can read those labels comfortably, staff can decide whether important information is still missing. What is the topic, and what is the main claim?
Reveal answer & reasoning
Topic: readable museum labels. Main claim: improve contrast on existing labels before adding more information.
The final sequence explains the priority. The passage does not advocate brighter lighting regardless of conservation needs, and “there are many museum objects” would be a related observation rather than its claim.
02 / UNDERSTAND & APPLY
Who is speaking?
Texts often stage a disagreement. The author may report a view to explain its appeal before limiting or rejecting it. Mark attribution: “the merchant argues” assigns a view to the merchant; “this overlooks” may introduce the author’s criticism. A concession accepts a limited consideration without accepting the other side’s entire conclusion.
Do not turn the first opinion encountered into the author’s position. Look at what the author ultimately explains or defends, including any conditions retained. A conclusion can occur at the start and then be supported, at the end after evidence, or across several connected sentences.
An author can also invent an objection for discussion: “A critic might ask whether later collection would disturb quiet study.” This anticipates a possible challenge. It does not establish that a real critic actually said those words, and presenting the objection does not mean the author endorses it. Read the response: an author may concede the risk, propose a separate entrance and still support a carefully limited service. Keep imagined voices, reported statements and the author’s own judgment distinct.
ORIGINAL WORKED EXAMPLE
A concession is not surrender
Original passage: A merchant argues that every market stall should close at dusk. Empty lanes, she says, would let cleaners work without weaving between customers. The need for an unobstructed cleaning period is real: spilling water around crowded stalls creates inconvenience and risks. Yet an early closure would also remove the only shopping opportunity available to some workers returning from late shifts. Their need does not disappear because it is inconvenient to the cleaning schedule.
A better arrangement would clean different lanes at different times, leaving a clearly marked route open. This would require coordination, and stalls could not simply ignore their assigned closure period. But the difficulty of organizing a staggered schedule is a reason to plan it carefully, not a reason to assume simultaneous closure is the only option. The market should therefore test staggered cleaning while monitoring both cleaner access and evening shopping access.
Does the author endorse the merchant’s blanket early-closure proposal?
Attribute the opening proposal to the merchant, not immediately to the author.
Identify the concession: cleaners really need usable space.
Find the objection: simultaneous early closure excludes some late-shift customers.
Read the alternative and final recommendation: test coordinated staggered cleaning with monitoring.
Answer No. The author accepts the cleaning need but recommends a monitored staggered schedule rather than closing all stalls at dusk.
ORIGINAL PRACTICE · 1
Original passage: “Waiting is the whole problem,” one passenger tells the station manager. The manager records the complaint but distinguishes two experiences. A passenger may wait ten minutes knowing when the bus will arrive, or wait the same ten minutes with no reliable information. Both lose time; the second also cannot plan a short errand or decide whether to walk. Better arrival estimates could reduce this uncertainty, though they would not make a delayed bus travel faster. Which view belongs to the passage’s reasoning rather than simply to the quoted passenger?
Reveal answer & reasoning
Better estimates can reduce uncertainty without necessarily reducing the actual delay.
The opening quotation collapses the problem into waiting. The later distinction is the text’s explanatory contribution. “Information eliminates delay” exaggerates it; “passengers do not care about waiting” contradicts it.
03 / UNDERSTAND & APPLY
Reasons and support structure
A reason answers “Why accept this claim?” An observation can become evidence when connected to a claim; an intermediate conclusion is supported by earlier material and then supports something further. A final conclusion is the main destination of that local argument, even if a later paragraph qualifies it.
Linked reasons need one another to make the intended case. “The room closes before these workers finish; they cannot leave work earlier” jointly explains their access barrier. Convergent reasons provide separate support: a shaded bench may help older visitors rest and also give volunteers a meeting place. Removing one does not automatically remove the other.
An argument map records the direction of support. Its arrows do not certify that an intervention causes an outcome, and they do not necessarily show time order. In the following hypothetical library case, a trial supplies a limited reason to consider a change. Staffing and protected quiet access constrain the recommendation; the trial does not prove that every nonuser would become a regular reader.

ORIGINAL WORKED EXAMPLE
A conditional main claim
Original passage: Entry to the neighbourhood library is free, but its collection desk closes before many late-shift workers leave their jobs. A notice about free membership does little for someone who cannot arrive while books are being issued. Several workers have asked whether they could reserve a book during the day and collect it later.
During a short weekend trial, some of those workers did use a later collection window. That experience shows a practical possibility, not the likely behaviour of every resident. The trial also brought a difficulty: people arriving at the desk talked near a room used for quiet study. Some study users asked for the earlier arrangement to be restored. Their objection concerned noise, rather than the mere presence of new readers.
The library should consider a brief late-collection service through a separate entrance, provided it can staff the desk and protect quiet access. Extending every library activity throughout the evening is neither necessary for this proposal nor justified by the trial. A limited arrangement could be assessed before any wider extension. Free entry matters, but access also depends on whether the service can actually be used at a suitable time and without undermining another legitimate use.
Choose the best main claim: A abolish quiet study; B retain current hours whatever the evidence; C consider a limited late-collection arrangement with staffing and quiet-access safeguards; D guarantee that later collection will make all nonusers readers.
Paragraph 1 identifies a time barrier that a zero entry fee does not remove.
Paragraph 2 offers limited positive trial evidence and a legitimate objection.
Paragraph 3 combines access improvement with safeguards and limited scale.
C accommodates all three roles. A reverses the safeguard; B ignores the proposed change; D adds a universal guarantee the passage rejects.
Answer C. The author supports a conditional, limited service change rather than unrestricted expansion or a universal prediction.
ORIGINAL PRACTICE · 1
Original passage: The garden committee is considering a bench under an existing tree. Older visitors sometimes need to pause while walking, and a shaded seat would give them a place to rest. Separately, volunteers currently stand near the gate while discussing their tasks; the bench could provide a meeting point away from arriving visitors. Either use would make the seat valuable even on a day when the other group was absent. The committee still needs to check that it will not block the path. Are the two stated benefits linked or convergent reasons?
Reveal answer & reasoning
Convergent reasons.
Resting and meeting are independently useful benefits under the passage’s explicit description. The path check is a feasibility condition, not a third claim that one group must be present for the other to benefit.

What each paragraph contributes
Name a paragraph’s job with a verb: introduces a problem, explains a mechanism, illustrates a pattern, raises an objection, qualifies a claim or recommends action. A paragraph may do more than one job, but a function answer should say how it contributes to the surrounding text.
A useful deletion test asks what would be missing if the paragraph vanished. Removing a case may reduce illustration while leaving the general argument intact. Removing the only explanation may leave observations without a connecting account. This test concerns organization, not whether every sentence is indispensable.
Some passages explain a sequence or compare methods without trying to persuade anyone to adopt a policy. Do not invent advocacy merely because the subject sounds important. An explanation can still have a clear main point: why records are needed, how a process works or what a comparison reveals.
ORIGINAL WORKED EXAMPLE
Purpose without a policy command
Original passage: A seed exchange once stored packets under the names used by the people who brought them. This was convenient because donors recognized their own terms. Over time, volunteers found that the same name sometimes referred to seeds with different appearances, while apparently similar seeds arrived under different names. A list of names alone could not tell a later volunteer which packet an earlier note described.
The exchange therefore began recording the donor’s name for the seed alongside photographs and observations about the packet. The record preserved local descriptions while making comparisons easier. It was a way to reduce confusion in the collection, not a test establishing which crop would perform best in every field. Soil, water and cultivation choices still differed between growers. Understanding this distinction explains both the value of the inventory and the limits of what one can learn from it.
What is the passage’s primary purpose?
Find the initiating problem: names alone can be ambiguous.
Trace the response: richer records make packets easier to compare and identify.
Retain the final limit: cataloguing does not determine universal crop suitability.
Answer To explain why a seed inventory uses more than names and what that inventory can and cannot establish. It does not demand one uniform crop policy.
ORIGINAL PRACTICE · 1
Original passage: The archive’s earliest catalogue listed boxes in the order in which they arrived. This helped staff locate a recent delivery but gave little guidance to a researcher following a subject across several collections. Later catalogues added subject entries while retaining the original box numbers, so that a reader could search by subject and staff could still retrieve the material. The account describes a change in organization and the problem it addressed. It does not compare the archive with other institutions or ask for a new budget. Is its purpose explanation, accusation or a demand for reform?
Reveal answer & reasoning
Explanation of a process and its purpose.
The text supplies a before-and-after organizational account. Nothing attributes misconduct, and no new reform is requested. A reader’s belief that archives deserve funding cannot substitute for textual evidence.
05 / UNDERSTAND & APPLY
Preserve the reach of the claim
A summary compresses wording, not the conditions that make the proposition true to its source. Track who, where, when, how many and under what conditions. “Some trial users found this useful” cannot become “everyone needs this”, and “may help” cannot become “must succeed”.
A qualified thesis is not merely a neutral list of pros and cons. It can favour a course of action while limiting its scale or identifying safeguards. To summarize it accurately, preserve both the direction and the restriction. Conversely, do not weaken a firm but bounded assertion into total indecision.
ORIGINAL WORKED EXAMPLE
The vivid case and the wider claim
Original passage: At the first session of a neighbourhood repair workshop, a participant brought a folding stool with a loose hinge. A volunteer showed how to identify the screw size and tighten the joint without splitting the wood. The repair took little time, but the participant had never been shown how to diagnose the problem. The case illustrated how a small gap in practical knowledge can leave a usable object abandoned.
Other items at the workshop presented a different difficulty. Participants understood what had failed but could not obtain compatible parts. Teaching more techniques would not by itself supply a missing connector. Nor would a shelf of parts help someone unable to identify which part was needed. A useful repair programme must therefore connect skill-sharing with a reliable way to find suitable parts. The stool is an accessible example of one barrier, not evidence that every repair is easy or that instruction alone solves the whole problem.
What is the main claim, and what role does the stool play?
Label the stool as an illustration of a knowledge barrier.
Read the second paragraph’s contrast: another barrier concerns compatible parts.
Notice the linked conclusion: skill-sharing and parts access address different needs.
Answer Repair support should connect practical learning with suitable parts access. The stool illustrates one barrier; it is not the whole thesis.
ORIGINAL PRACTICE · 1
Original passage: During last year’s small local festival, several visitors asked for a quiet opening hour. Organizers think a similar arrangement may be useful next time, but they have not yet checked demand or found enough staff to supervise a separate period. They propose offering the hour if both checks are satisfied. The regular programme would continue afterwards, and the proposal does not require every future event to use the same schedule. Is “The organizers require a quiet hour at every event” an accurate summary?
Reveal answer & reasoning
No. The proposal is conditional and event-specific.
The inaccurate summary replaces “if demand and staffing permit” with an unconditional requirement and extends one proposal to every event. Both changes alter the main claim rather than merely shorten it.
06 / UNDERSTAND & APPLY
Use signals without being ruled by them
Words such as however, therefore and for example signal relationships, but do not locate the main point mechanically. However can mark a small contrast within a supporting example. Therefore can introduce an intermediate conclusion that becomes a premise for the larger argument.
Read the propositions on both sides of a signal. Ask what changes: the speaker, the strength of a claim, the proposed explanation or the recommended action. Then place that move in the whole passage. A final sentence may express a detail or limitation rather than replace everything before it.
ORIGINAL PRACTICE · 1
Original passage: The survey team tested water at three public taps on one morning. Two readings met the stated test threshold; one did not. However, the third tap had just reopened after maintenance, unlike the others. The team therefore decided to repeat that test after normal operation resumed. A repeat would help interpret this unusual reading, but even a satisfactory result would describe only the tested places and times. The town-wide water network contains many more outlets. What is the main limit on the findings?
Reveal answer & reasoning
The observations concern a small set of outlets and times, so they cannot establish the state of the entire network.
“Therefore” leads to the intermediate decision to repeat one test. “However” introduces a relevant difference. Neither word makes that local decision the passage’s widest conclusion; the final scope caution must be retained.
07 / UNDERSTAND & APPLY
Test the option, not its appeal
A main-point option can fail in several different ways. It may be too narrow, reporting one example; too broad, universalizing a bounded conclusion; reversed, adopting the view the author rejects; or imported, adding a claim that is absent even if it sounds sensible. Explain the mismatch rather than simply labelling an option wrong.
Prefer the option that accounts for the passage’s important parts with the fewest unsupported additions. This is not a rule to choose the longest or vaguest answer. An accurate answer must identify a meaningful relationship and retain the essential qualification. A true detail still answers a detail question rather than a purpose question.
ORIGINAL WORKED EXAMPLE
Two displays, two questions
Original passage: A reservoir dashboard can show the amount of water recorded today as a single prominent number. That display is useful to someone asking about the latest available reading. It is less helpful to a reader trying to discover whether the level has been rising steadily, fluctuating or falling after a brief recovery. A second display traces readings across the week and makes that sequence easier to inspect.
The weekly display has its own limits. A reader looking only for the current figure may have to search for the final point, and a poorly labelled graph can make the scale difficult to interpret. Neither design is better independently of the question being asked. A service could present a clearly dated latest reading alongside a labelled short trend, allowing users to inspect either without confusing them. This would distinguish current state from recent change rather than asking one display to answer every question equally well.
Choose the best summary: A current readings are useless; B graphs always communicate better; C current-value and trend displays serve different questions and can complement each other; D the reservoir will soon run dry.
The first paragraph assigns different questions to the two displays.
The second acknowledges limits on each and suggests a complementary presentation.
C captures the distinction and synthesis. A contradicts the stated use; B removes qualification; D predicts an outcome with no supplied evidence.
Answer C. The passage compares information needs rather than declaring a universally superior format or forecasting water levels.
ORIGINAL PRACTICE · 1
Original passage: A school caretaker found a broken hinge on a tool cupboard during a routine check. The fault was minor, but checking nearby fittings revealed several other loose screws. The head teacher used the incident to explain why brief regular inspections could catch wear before equipment became difficult to use. She did not say that every tool was damaged or that all repairs could be completed immediately. The hinge made the maintenance issue concrete. What is the hinge’s function in the argument?
Reveal answer & reasoning
An illustrative case that motivates regular inspection.
The case shows how one check can reveal a wider maintenance need. It neither proves universal damage nor establishes that all repairs are easy. The function question asks why the detail is included, not merely what was broken.

Build and check a one-sentence summary
Use a short routine: identify the question, mark the author’s position, assign paragraph roles, draft a one-sentence summary, and check its scope. Finally ask whether each major paragraph makes sense as support, objection, explanation or qualification of that summary. If a paragraph seems irrelevant, either it is a deliberate aside or your summary may be incomplete.
Keep purpose and detail apart. “What changed?” may ask for an explicit fact; “Why does the author describe the change?” asks about its role. You can disagree with the author and still accurately identify the argument. This lesson teaches that reading task; deciding whether the evidence is strong enough is a separate evaluation task.
ORIGINAL PRACTICE · 1
Original passage: A town has produced a detailed map for residents who need to identify service boundaries and local facilities. Visitors often ask different questions: how to reach a few landmarks and where to change buses. Compressing all the information onto a single small sheet has made both sets of labels hard to read. Removing local information would help visitors but leave residents without material they use.
The design team proposes two selectable map layers built on the same street base. One emphasizes visitor routes; the other shows local services. A user could switch between them, and a printed desk copy would remain available for people without a device. The proposal does not assume that every visitor and resident has identical needs within their group. It offers a way to manage two common sets of questions without making one dense display serve all of them at once.
Choose a summary: A remove resident information; B use two accessible map layers to meet different common needs; C residents should use only paper; D one identical map necessarily suits everyone.
Reveal answer & reasoning
B. The proposal separates common information needs while keeping access to both layers and a paper alternative.
A deletes a need the author protects. C converts a fallback into an exclusive rule. D restates the approach whose practical problem motivates the change. B explains both the original difficulty and the proposed response without claiming every user is identical.
